A single active neuron is not sufficient. ~100,000 simultaneously active neurons are needed to generate a measurable M/EEG signal. Pyramidal cells are the main direct neuronal sources of EEG & MEG signals. Synaptic currents but not action potentials generate EEG/MEG signals (AP bidirection, cancel, and time constant is small, cannot accumulate.) pyramidal cell bodies (somas) average around ~ 20μm.
